Danica Patrick let it slip Wednesday that she will drive the Indianapolis 500 for Ed Carpenter Racing.

Patrick was upset about the error, dropping the microphone at Daytona 500 media day and mumbling in disgust.

"Oh, (shoot), did I just say that out loud?" Patrick said.

She then put the mic in her lap and cursed somewhat under her breath. It took several seconds for her to compose herself.

"I've never done that in my career," she added.

She was agitated as she answered a few more questions before saying, "I better shut up and leave. I'm going to be in trouble."

Patrick rejoined longtime sponsor GoDaddy to run the final two races of her career, a feat she has dubbed the "Danica Double." She will race the Daytona 500 for Premium Motorsports and previously said she was close to announcing plans for the Indy 500 in May, her finale.

But instead of getting a highly anticipated reveal, Patrick accidentally leaked the news in front of about two dozen media members.

ECR had been the likely landing spot for Patrick. The team is in part owned by Tony George, the founder of IndyCar and chairman of the family group that owns Indianapolis Motor Speedway. Carpenter is George's son.

ECR's primary focus each season is the Indy 500, and its cars are always competitive in May. Carpenter won consecutive poles in 2013 and 2014 and has a career-best finish of fifth. The pairing with Patrick benefits the speedway and the race, both owned by George, and gives Patrick a strong entry for her final race.

Patrick will be in a third car for ECR, joining Carpenter and Spencer Pigot.

But the rabbit's foot he stuck in his pocket before the 2017 season finale at Homestead-Miami Speedway has him reconsidering his views.

Truex won at Homestead to clinch his first championship. Former NHRA racer Darrell Gwynn gave Truex the lucky charm before the race.

Truex brought it with him to Daytona International Speedway, but hasn't decided whether to break it out for the season-opening Daytona 500.

"I've thought it about it a little bit," Truex said Wednesday at Daytona 500 media day. "I don't know if I need to keep it for the big ones, maybe just keep it in case we get to Homestead again. I don't want to use it up. I mean, it's been sitting there for 20-something years gathering luck and it worked at Homestead, so I don't want to push my luck."

What if someone wants to borrow it?

"No," he quipped.

Darrell "Bubba" Wallace is set to become the first black driver since 1969 to start the Daytona 500.

Wallace faced perhaps the biggest media contingent of the day Wednesday, with more than two-dozen writers holding selfie sticks and mobile phones in the face of the rookie driver.

Wallace played it cool. He said he welcomed the pressure that comes with the magnitude of his start.

"I'm just a race-car driver," Wallace said. "I'll whup their ass any day."

Wallace will drive the No. 43 car made famous by Hall of Fame driver and team owner Richard Petty.

Wallace had fun with the topic of the day - who will become NASCAR's next most popular driver? Most drivers answered Chase Elliott. Wallace smiled and did a playful double-take with a reporter before he answered:

"Hopefully me," he said, smiling.

Wallace's journey has been documented in "Behind the Wall: Bubba Wallace," a new series that debuts Thursday on Facebook Watch.

Denny Hamlin is no longer on the NASCAR drivers' council he helped create.

Hamlin said at Daytona 500 media day Wednesday that he was not voted to the council for 2018.

But he still feels like he has a voice in the Cup Series garage.

"There are issues that I like to have a voice on, but I still have that voice internally with NASCAR and still get invited to plenty of private meetings with them on issues," Hamlin said. "Not a whole lot of change as far as my role."

The council has nine drivers representing each of NASCAR's three manufacturers, Chevrolet, Ford and Toyota.

Elliott Sadler is ready for another shot at an elusive championship.

The 42-year-old Xfinity Series driver has finished second four of the last seven years, including back-to-back seasons. He finished fourth or better in six of those seven years.

He drives for close friend Dale Earnhardt Jr. at powerful JR Motorsports.

Sadler has being striving for a championship since breaking into the national series in 1995. He drove 12 full-time seasons in the Cup Series, finishing as high as ninth in 2004, and has driven nine full-time seasons in the second-tier, Xfinity Series.

He knows the day is coming that he will hang up his helmet, but he doesn't want it to be until after a title. He watched Earnhardt and fellow 40-something drivers Jeff Gordon, Tony Stewart and Matt Kenseth walk away over the last three years.

"I've talked to them guys," Sadler said. "When do you know deep down in your heart that, `Hey, it's time for me to do something else?' I have that in mind. I understand what that feeling is probably going to be like.

"Right now, I don't have it. I still want to race and I still want to be competitive. I still want to do the things it takes to be a good race-car driver. I want to be in the gym. I want to watch film. I want to do those things. I think once that day comes where, `Ah, I don't feel like going to the racetrack, then I'll know it's time to step away. But right now it has not come to that point."

The sanctioning body reduced the number of crewmembers allowed over the wall from six to five, meaning fewer people making changes when every second counts. NASCAR also instituted a universal air wrench that is heavier and slower. The new rules made their debut in the Clash at Daytona last weekend.

"I didn't see any pit stops the other day that were very good," Truex said. "Ours were awful. I'm sitting there like, `Oh my God. This is way worse than I anticipated.' I felt like was sitting there for a minute. And then I came out with the three guys I came in with, so I'm like, `OK, so we all sucked.'"

The loss of a crew member is expected to add at least a couple seconds to a typical pit stop. The additional time also allows teams to get creative with how to perform the same work with fewer people. An unexpected byproduct is more injuries from pit crews handling a heavier workload.

"All I've heard all offseason is how difficult it is, how many guys are getting hurt, the guns are so slow, the guns are this," Truex said. "It's going to be bad. I feel it's going to take a while to figure out."

Seven-time champion Jimmie Johnson has no retirement date in sight.

Johnson has watched fellow 40-something drivers Jeff Gordon, Tony Stewart, Matt Kenseth and Dale Earnhardt Jr. all leave the sport over the last three years. But he's not ready to join the NASCAR star exodus quite yet.

"For me, I feel like, sure, I could stop; I've accomplished so much," Johnson said at Daytona 500 media day. "But what else am I going to do? I'm going to find something else to race. I am a racer at heart and I want to compete and I feel like I can accomplish more in the sport and win more races and compete for more championships and win more championships. I don't feel that it's time yet.

Johnson said his desire to compete is as "intense as ever" as he continues his chase of a record eighth NASCAR Cup championship. Johnson, who won the 2016 crown, is coming off the worst season of his career. He won only three races - none after June - and finished 10th in the final points standings.

The Daytona 500 has gone dry.

Former NASCAR champions Brad Keselowski and Kevin Harvick, who usually sport beer brand sponsors logos on their hoods, have non-alcoholic sponsors for the Daytona 500.

The Daytona 500 will be the first once since 1982 without a beer-sponsored car in the race.

Miller Lite will still serve as primary sponsor for Team Penske and the No. 2 car driven by Keselowski at select races. Same with Busch and Harvick's No. 4 Ford.

"It's not like they're not active," Harvick said. "You go everywhere in this town and Busch has pretty much taken over the town. You would never know Busch is not on the car when you drive around town and look around the racetrack."

He Said It:

"Joey is one of those guys you could kick in the (groin) and he'd walk away smiling."

It's a thorny issue for Brad Keselowski. Does it matter that he is the favorite to win the Daytona 500?

Keselowski can't bet on himself.

"I'd be Pete Rose," Keselowski said. "I don't think it should be illegal to bet for yourself. It should be illegal to put against yourself."

But is their pressure as the favorite?

"No, because I don't have any money on it," Keselowski said, laughing.

Kevin Harvick has high expectations for budding star Chase Elliott.

The 2014 NASCAR Cup champion called Elliott the "biggest tie to our grass-roots NASCAR fan." Elliott is the 22-year-old son of Hall of Fame driver Bill Elliott. Both hail from Dawsonville, Georgia.

"I feel like he's one of the most important ingredients in what NASCAR racing does going forward because of his family name," Harvick said at Daytona 500 media day. "He has the legacy that's already been built in this sport by his dad. He's come into this sport with a great name and already proven that he's going to be competitive. He has those southeast, NASCAR ties to those core fans that none of the rest of us will ever have. He's the guy."

Elliott, entering his third full season at Hendrick Motorsports, in winless in 77 career Cup starts. He has 12 top-five finishes last year, including five runner-ups.

"When he wins the first time, you're going to see things that you haven't seen in a long time from fan reaction and just enthusiasm about this sport," Harvick said. "And when that happens, it's going to be good for all of us."

The green flag is about to drop on Daytona 500 media day.

There's plenty to talk about heading into Sunday's race. The field has undergone a dramatic youth movement, and new stars seem to be the sport's focus. Alex Bowman is on the pole for the season-opening race and fellow Hendrick Motorsports teammate William Byron is set to make his Cup series debut.

Kurt Busch will try to defend his Daytona 500 championship, and Martin Truex Jr. opens defense of his 2017 series title.

Darrell Wallace Jr. will make history as the first black driver since 1969 to start the Daytona 500.

Danica Patrick is still around, at least for one more race. She'll make her final NASCAR start as part of the "Danica Double" that has her ending her career back in open-wheel racing at the Indianapolis 500.
